Last month Betacup challenged its participants to present innovative ideas on how to eliminate paper cup consumption through the design of a more convenient alternative to the reusable coffee mug. The judging process was split into two categories: the Jury Prize and the Community Prize.

The Jury Prize of $10,000 was awarded by a panel of independent experts to a single submission. The Community Prize of $10,000 was awarded to the top 5 ideas voted on by the community, which consisted of all the participants.

After filtering through 430 submissions from all over the world, the jury of the Betacup Challenge Contest, sponsored by Starbucks, has finally revealed the winners.

The Karma Cup concept encourages people to use reusable mugs with the notion that good choices in life will come back to reward you with good karma. Every tenth person to use a reusable cup gets a free cup of coffee. Law of statistics says that the more you use a reusable cup, the more likely you are to get that free cup of coffee.
